The research on the formation of SFCA in the process of cooling and solidification is seldom reported. Therefore, the sintering crystallization process was observed by using scanning electron microscopy (SEM), optical microscope. The effect of different cooling systems on the microstructure and phase composition of the sinter was investigated to find the appropriate cooling rate to improve the metallurgical properties of sinter. The experimental result shows that the crystallization of calcium ferrite is well with decreasing of the cooling rate. There is a large number of hematite with the structure of interconnected crystal. Some research shows that it can't get good results to reduce the cooling rate below 800℃, because the slower cooling rate is beneficial to the transition of 2CaO•SiO2 ,and the transition decreases the strength of the sinter. The slower cooling rate is not conducive to the quality of the sinter. Therefore, the appropriate cooling rate (air cooling) from the microscopic structure is advantageous to the sintering.
